Abstract

This paper presents an application of vector control strategy for 1.2MVA IGBT traction drive for electric railway vehicle. The vector control requires the control of the phase and amplitude of output voltage vector[5]. But in case of traction system far railway vehicle, the one-pulse mode is used in order to utilize the link voltage fully[8]. So it is impossible to control the flux axis current and the torque axis current instantaneously and independently. So this paper proposes the vector control strategy with slip-frequency control at one-pulse mode. And precise switching technique between the two different control structures has been proposed. And the strategy was verified by experimental result with 1.2MVA IGBT inverter with four 210㎾ induction motors.
